Inside of `<tc:row>` and `<tc:column>` tags a `<tc:style>` can be used to set a CSS class or style to a specific row. In this example the rows are green (via customClass `planet`) when the object orbit is 'Sun'. The cell in the year column is blue, when the objects discovering year is older than 1900 (custom class is `old-planet`).

For responsive display or hiding columns, see the styling example.
